Excel List Row Filter Query Broken?

[JeddPearce]

I've got an Excel sheet with a bunch of rows grouped by a specific column. E.g.

GroupDateID	Product
41	Watermelons
42	Apples
42	Bananas
42	Cherries
42	Dates
43	Elderberries

I have a flow that uses "List rows present in a table" operation, with a filter query of "GroupDateID eq '42'". This should always return a list of Apples, Bananas, Cherries, and Dates. Except sometimes it returns Apples and Dates, sometimes Bananas and Cherries, and sometimes it doesn't return anything at all. If I remove the filter query entirely, they all return (along with all the other IDs I don't want), but it's getting the data. It's only when I filter that I get weird results.

To make matters stranger, I didn't see any problems with this until several weeks ago. Then the filter results started getting inconsistent, and now the filter results are always null. 

Was there an update that broke the filter functionality? Is my ODATA query somehow wrong? What on earth could be happening here?
EDIT: Here's a weird scenario I found: If I go back to an earlier GroupDateID that worked previously and edit the contents of that row, the edited row is found by the operation with the changes. But if I copy that row, it only finds the original row not the duplicate (even though their contents are exactly the same). I'm flummoxed.

hi @JeddPearce  to compare string or Text you have to add '' but for number is wihout

Numbers = GroupDateID eq 42

Text = GroupDateID eq '42'

I simplified it for this thread, but this is the expression I'm actually using:

StartDateID eq '@{div
(
  sub
  (
    ticks(formatDateTime(utcNow(), 'yyyy-MM-ddT00:00:00')), 
    599264352000000000), 
  864000000000
)}'

So it's producing the result of:

StartDateID eq '44638'

But even if I manually try it with "StartDateID eq 44638" I don't get any results (today there are 14 results that should match).

Pretty sure the expression you use will return a number, and the value you are comparing it to is a string

Try: StartDateID eq string(44638)  to check if this is true, and modify your expression to

StartDateID eq '@{string(div
(
  sub
  (
    ticks(formatDateTime(utcNow(), 'yyyy-MM-ddT00:00:00')), 
    599264352000000000), 
  864000000000
))}'

if needed

That gives me this error:

An unknown function with name 'string' was found. This may also be a function import or a key lookup on a navigation property, which is not allowed.
     inner exception: An unknown function with name 'string' was found. This may also be a function import or a key lookup on a navigation property, which is not allowed.

this returns true for me

I hired Microsoft support to look into the issue, and they have no idea what caused the problem, but the solution was clear and reconnect the operation. Once everything was reconnected it pulled the data as intended.
